To clean the main filtering element, proceed as follows:
blow off main filtering element 5 with dry compressed air until dust is completely
o
removed. In order to avoid rupture of the material of the main filtering element, air pressure
shall make 0.2 to 0.3 MPa. Air jet shall be directed from clean air side to unclean air side,
as arrows show in figure 5.4.32. During maintenance it is required to protect filtering ele-
ments against mechanical damages and oiling.
check the main filtering element for possible damages (shutter is ruptured, bot-
o
tom came unstuck);
clean the sealing ring of the main filtering element with a wet wipe and install
o
the main filtering element into the air cleaner housing.
ATTENTION: IT IS FORBIDDEN TO BLOW OFF THE MAIN FILTERING ELE-
MENT WITH EXHAUSTS, WASH AND DUST IT!
ATTENTION: THE CLEANED MAIN FILTERING ELEMENT DOES NOT HAVE
THE EFFICIENCY OF A NEW ONE!
1 – main filtering element; 2 – inbuilt unit "multi-cyclone".
ATTENTION: AFTER THE AIR CLEANER IS ASSEMBLED IT IS REQUIRED TO
CHECK ALL CONNECTIONS OF THE INLET DUCT FOR AIR TIGHTNESS.
To check air tightness, use device КI-4870 GOSNITI or its analogue. If the device is
not available, check the connections for air tightness visually. Damaged connection mem-
bers shall be replaced.
IT IS FORBIDDEN TO OPERATE THE TRACTOR WITH THE INLET DUCT HAV-
ING AIR LEAKAGE.
Air leakage in the circuit of air supply to the turbocharger may adversely affect read-
ings reliability of the impurity indicator, as a result significant volume of unpurified air with
high concentration of dust leading to accelerated wear out of the engine sleeve group may
get into cylinders through the turbocharger.
